Grinding time for ball mills - Grinding & Classification ...
This is the instantaneous residence volume for pulp. Next compute the volumetric flow of slurry into your mill, as m³/h or L/s (match whatever volume units you used in the first step). Now divide the instantaneous volume by the vol flow (cancelling the vol units) and you are left with time units; this is your residence time.
The How, What, and Why of Grinding SCMs
Due to the short residence time, changing from one product mix to another is a relatively quick and simple process compared to ball mills. Drying is incorporated and efficient. To put it bluntly, if the cement industry truly hopes to achieve net zero carbon by 2050, VRMs are the only way to get there for cement grinding.
